Remove Praetorium

[Rongway]

Then don't do mentor roulette if you don't want to get Praetorium

I will happily run DR:Mentor where I'm actually useful twenty times in one day despite finishing the mount achievement five or six years ago, simply because it's a "surprise me with (almost) anything" roulette.

Still not going to sit and do literally nothing for the majority of a half hour Praetorium run. Mentors are not needed to fill DR:MSQ duties because there is a super limited roulette that is just for those three duties and which compensates people for their time. DR:MSQ duties don't belong in DR:Mentor.
